Van der Waals heterostructures,composed of individual two-dimensional material have been developing extremely fast.Synthesis of van der Waals heterostructures without the constraint of lattice matching and processing compatibility provides an ideal platform for fundamental research and new device exploitation.We review the approach of synthesis of van der Waals heterostructures,discuss the property of heterostructures and thoroughly illustrate the functional van der Waals heterostructures used in novel electronic and photoelectronic device.
